Perfect Binary Tree

Famous quotes containing the words perfect and/or tree:

    By the “mud-sill” theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be—all the better for being blind, that he could not tread out of place, or kick understandingly.... Free labor insists on universal education.
    Abraham Lincoln (1809–1865)

    On a tree by a river a little tom-tit
    Sang “Willow, titwillow, titwillow!”
    And I said to him, “Dicky-bird, why do you sit
    Singing, ‘Willow, titwillow, titwillow’?
    Is it a weakness of intellect, birdie?” I cried,
    “Or a rather tough worm in your little inside?”
    Sir William Schwenck Gilbert (1836–1911)
